Popularly associated with midcentury modernist lounging, the Butterfly Chair began life as a wood-framed folding chair used during the Crimean and Boer wars and was patented by the British in 1877. Fifty or so years later, three Argentine architects—Jorge Ferrari-Hardoy, Antonio Bonet, and Juan Kurchan—replaced the wood with a single length of steel and exhibited the chair at a furniture fair in Buenos Aires. It caught the eye of MoMA's industrial design curator Edgar Kaufmann Jr., who bought one for the museum and one for his parent's new country house, Fallingwater, designed by their friend Frank Lloyd Wright. Knoll acquired the US production rights in 1947, and about 5 million chairs were sold during the 1950s alone.

The popularity of the Butterfly Chair continues apace and today it is made by a range of manufacturers worldwide, including French company Airborne, which has been producing the chairs since 1951 and has come out with a couple of variations on the theme (it's also faithfully reproduced in the US by Circa50, and will soon be available at Steele Canvas).
